Conclusion
Currently, the frequency of droughts remain the same, however the duration of its
stay is increasing. The economic and social impacts of drought are worsening. The
proposed definition is based on the threshold precipitation which has been selected
keeping in view the annual mean precipitation of Pakistan. The map shows most
drought prone regions of Pakistan where drought conditions have persisted for 31
years (1980-2010). This map may be helpful for the authorities to make policies
about drought mitigation and preparedness and implement them in the danger
zones. The south eastern portions of Pakistan are desert regions and are currently
in the grip of a severe drought. Anjum et al.(2010), mention rightfully in their
research that Thar receives 100-500 mm of rainfall annually. Akhtar and Arshad
(2006) state that mean annual rain in Cholistan ranges from less than 100mmto
200 mm, which implies that drought threshold defined in this paper is clear
declaration of meteorological drought state. Thus, we conclude that the current
drought episode of Thar is creeping into Cholistan too and suggest the government
to take necessary precautionary measures to minimize the loss of life and property
in these areas. The crisis management policy of the government needs to be
urgently changed to drought preparedness. According to Bates, Kundzewicz, Wu,
Palutikof (2008), drought frequency around the world is going to increase, thus it
is important to understand the phenomenon, identify its causes and quantify
drought patterns. Thus, it is hoped that this research work will prove as a
threshold for further research in drought studies
